In the project I’m managing we’re evaluating Pivotal Tracker as our online Scrum tool. I wanted the client to have a good view of our progress so I gave him viewing rights to it. Didn’t work out that well. He couldn’t map the dev teams stories to the feature set overview we had written and prioritsed.
Pivotal Tracker has a friendly API which lets you access your data. One could build a special view outside of Pivotal Tracker that shows bigger features, and gets the data by aggregating several stories. I’m thinking something along the lines of a Scrum or Kanban board, but for the customer.
There are other parameters my client wants to see that aren’t really part of Scrum. Like our time budget and overall project progress. They too would be part of the “view”.
